92 vr4 pedal response

[3000crazy]

I have a 92 vr4 that starts and idles great. When you press the pedal it coughs and sputters unless you get it pretty high rpm (but getting it there is a trick). I doesn't like pedal movement lol..... i just replaced the fuel filter a couple hundred miles ago, ecu has been rebuilt, and had the 60k done... ran fine after all these but late last year it started this stuff. It's been in storage since last fall. Now it's coming toward show season and I'd like to be able to drive my car...ideas?

Throttle position sensor maybe?

Pull your filter first and look for mice nests since it's been stored.

Then check for boost leaks, y-pipe on tight?

Is the fuel pump resistor relay still stock. If so bypass that bitch.

you guys are great!!! the y-pipe (factory unit..aka POS) was on tight, but the gasket for it was all tucked over on itself thus no seal... Now I still have a massive boost leak somewhere because I get "popcorn" when I get into boost, but this I can deal with now that the car will pull itself without dieing...

Can also be bad gas from sitting too long, if you didn't put stabilizer in it. I had the same after my car sat about 8 months, popping into and coming off boost. Once the tank of gas was gone, filled it up with fresh 93, no more problems.

RobBeck boost leak tester, if you don't already have one.

If you were runnng a wide band you would see it as well. A boost leak between turbo and throttle body you will end up rich. If your boost leak (vaccum) was between turbo intake and Mass, you will be nuts lean. Boosting under those (lean) conditions will hurt you bad.
You can burn a hole in your one of your pistons.
